Maximum efficiency when recycling scrap material

Optimizing process reliability with Endress+Hauser

Perfect planning and a tight timetable are indispensable when recycling scrap material. Cargo ships, freight trains and trucks deliver scrap metal by the ton and then take loads of the best recycled steel away. Within the space of a few hours, the old scrap metal is subjected to scorching heat; at tapping temperatures of over 1600 °C (2900 °F) in powerful electric arc furnaces, for secondary-treatment in ladle furnaces, then in casters. Finally, the roller mills spit out top-quality steel.

Customer challenge

An optimum material flow is mandatory and each individual step in the workflow must be right. For the energy-intensive operation of steel mills, process reliability, resource and energy efficiency and environmental impact take top priority. The development of efficient technologies is economically very significant, for the energy costs can represent a third of the influenceable turnover in a steel mill.

This is where Badische Stahl-Engineering (BSE) comes into play: facilities and machines that have been tested under stringent long-term conditions are optimized for the users and supplied to steel mills all over the world. Thanks to the strong inventive spirit and the hunt for more efficient technologies, new innovations are being developed.

Our solution

For optimizing process reliability with ‘High-tech, made by Badische Stahl-Engineering GmbH’, Endress+Hauser flowmeters, pressure and temperature sensors play a part. They perform their tasks reliably in the tough, hot environment. They assist with the search for leaks and with the control and analysis of compressed air, compressed natural gas, oxygen and water. They help to improve efficiency with the chemical energy input into the furnace.
